We started the day around dawn in the Bear Creek Greenbelt.  It’s a good time to spot raccoons, or be spotted by them.


Both westside (west of Estes) owlets had branched out to a tree west of the nest tree:

Mama was keeping watch nearby:

At the end of our walk we saw another mammal:


Then we drove over to the Grand Junction area.  At Rabbit Valley we saw a Rock Wren:

Wildflowers and cactus were blooming:


At Colorado National Monument we spotted a Say’s Phoebe along the Alcove Trail:

I finally saw my first ducklings of the year in the Bear Creek Greenbelt. Twenty at once, in fact!

Manky Mallard is still a fixture, still paired up.

Late this afternoon I went into the Bear Creek Greenbelt to look at the westside (West of Estes) Great Horned Owl nest.  The nest is gone!  Perhaps it broke apart as the owlets got larger.  It had been a Cooper’s Hawk nest last year, so it wasn’t as large as, say, a Red-tailed Hawk nest.  The two owlets are clinging to branches.  Here’s Mama Great Horned Owl with the two owlets:

Another view:

It was very hot (high 80s) and sunny.   At one point, Mama Great Horned Owl flew to a more shaded branch on a nearby tree.  To cool down, she dropped her wings and employed gular fluttering (where she opens her mouth and vibrates her throat tissues to rapidly pump air back and forth in her system, a form of evaporative cooling).

However, an American Crow showed up and harassed her.

Meanwhile, back at the former nest, one of the two owlets found shade the best it could and the other worked on its climbing skills.

Mama Great Horned Owl eventually flew back to the former nest and perched above the owlets, perhaps to shade them and shield them from the crows.

Today I joined a Denver Field Ornithologists trip to Parker Regional Park, led by John Breitsch.  I saw 45 species of birds, including this White-crowned Sparrow (which is a Mountain subspecies, not a Gambel’s):
